Could you mention a few of the stuff you did try if you remember them. That way we don't need to go the same hurdles and can reach the crux of the problem faster.
And becuase life is so special we don't know exactly which LUAs do not work with patch 3, right? Though I would assume it would be the LUAs that arn't game breaking. The LUAs that belong to each individual Masari, Novus and Hierarchy unit, structure, power,etc. Those that are part of the GUI and UI.
I think I should make a new thread and people should post there which LUAs don't work with UaW on patch 3 so that way we can weed out what doesn't work and not waste time on it or know which we should try to fix.
